THlLL-COU-PLING.

SPECIFICATION forming part of Letters Patent No. 592,638, dated October26, 1897. Application filed June 24, 1896- Serial No. 596,697- (Nomodel.)

To all whom it may concern:

Be it known that I, EDWARD I. MEAD, a citizen of the United States ofAmerica, and a resident of Mamaroneck, in the county of Westchester andState of New York, have invented a new and useful Improvement inThill-Couplings, of which the following is a specification.

My invention relates to thill-couplings, and its object is to provideimproved means for holding in place the jack-bolts by which thethill-irons are secured to the clips.

The invention consists in the novel construction and combination ofparts hereinafter fully described and claimed.

In the accompanying drawings, Figure 1 is a plan view of achill-coupling constructed in accordance with my invention. Fig. 2 is alongitudinal section on the line 2 2, Fig. 1. Fig.3 is a transversesection on the line 3 3, Fig. 1. Fig. t is a similar view on the line 44, Fig. 1.

In the said drawings the reference-letterA designates the axle of avehicle, and 'O the clip thereof, formed with the usual screwthreadedends 0, with which engages the plate D, held in place by nuts (1. Theseclips are formed with forwardly-extending apertured lugs L -L, throughwhich passes the headed jack-bolt B. This bolt also passes through thethill-iron S. The parts so far described may be of any ordinary orsuitable construction, as they form no part of my present invention.

Secured to the inner lug L, at the inner side thereof, are two verticalarms B parallel to each other, with a small space therebetween, andpivoted to the upper ends of these arms is a blade B. ,These arms areprovided with a knife-spring b,which engages with the inner end of saidblade and holds it in an open or closed position, like an ordinarypocketknife. Secured to inner arm B is an inwardly-extending plate 19formed with a rectangular opening b through which the said inner lugprojects. Passing through the upper part of this plate is a set-screw s,by which the same and the arms secured thereto are secured to and heldin place on the clip.

In use after the jack-bolt has been passed through the lugs the blade Bis turned down, so as to lie just behind the head of the bolt, so thatthe bolt cannot be removed from the lugs until said blade is opened, asin Fig. 3, thus rendering the use of a nut on the opposite end of thebolt unnecessary.

The device can be readily applied to the ordinary thill-clips now in usewithout the necessity of taking off the wheel.

Having thus fully described my invention, what I claim is 1. In athill-coupling, the combination with the clip and the apertured lugs, ofthe vertical arms, the blade pivoted thereto, the inwardly-extendingplate secured to one of said arms, having an opening therein throughwhich one of said lugs passes and the setscrew passing through saidplate andbearing upon said lug, substantiallyas described.

2. As an improved article a device for holding in place the jack-boltsof thill-couplings, consisting of the parallel arms, the blade pivotedthereto, the plate secured to one of said arms, having an openingtherein and thesetscrew passing through said plate into the opening,substantially as described.

In testimony that I claim the foregoing as myinve'ntion I have signed myname, in presence of two witnesses, this 18th day of June, 1896.

EDWVARD I. MEAD.
